Self-Powered Speed Sensor for Turbodrills Based on Triboelectric Nanogenerator
Turbodrills play an important role in underground energy mining. The downhole rotational speed of turbodrills is one of the key parameters for controlling the drilling technology. Therefore, it is necessary to measure the rotational speed of the turbodrills in real time. However, there is no dedicat...
